bio_add_page - attempt to add page to bioSYNOPSIS¶
int
bio_add_page(struct bio * bio,
struct page * page,
unsigned int len,
unsigned int offset);
ARGUMENTS¶
biodestination bio

DESCRIPTION¶
Attempt to add a page to the bio_vec maplist. This can fail for a number of reasons, such as the bio being full or target block device limitations. The target block device must allow bio's up to PAGE_SIZE, so it is always possible to add a single page to an empty bio.COPYRIGHT¶
